Silver halide color photographic photosensitive material containing a yellow coupler

Abstract

The present invention relates to a silver halide color photographic photosensitive material which contains a coupler which can be represented by formula (1): ##STR1## wherein X1 and X2 each represent an alkyl group or a heterocyclic group, Y represents an aryl group or a heterocyclic group, and Z represents a group which is eliminated when the coupler which is represented by formula (1) reacts with an oxidized form of a developing agent.

What is claimed is: 
     
       1. A silver halide color photographic photosensitive material which contains a coupler represented by formula (1): ##STR15## wherein X1 and X2 each represent an alkyl group or a heterocyclic group, Y represents an aryl group or a heterocyclic group, and Z represents a group which is eliminated when the coupler which is represented by formula (1) reacts with an oxidized form of a developing agent. 
     
     
       2. The silver halide color photographic photosensitive material of claim 1, wherein the alkyl groups of X1 and X2 are linear chain, branched or cyclic, substituted or unsubstituted alkyl groups which have from 1 to 30 carbon atoms. 
     
     
       3. The silver halide color photographic photosensitive material of claim 1, wherein X1 and X2 are substituted alkyl groups and the substituents are selected from the group consisting of alkoxy groups, halogen atoms, alkoxycarbonyl groups, acyloxy groups, sulfonyl groups, carbamoyl groups, sulfamoyl groups and aryl groups. 
     
     
       4. The silver halide color photographic photosensitive material of claim 1, wherein X1, X2 and Y represent heterocyclic groups having three to twelve membered, saturated or unsaturated, substituted or unsubstituted, single ring or condensed ring heterocyclic groups which have from 1 to 20 carbon atoms and which contain at least one nitrogen atom, oxygen atom or sulfur atom as a hetero atom. 
     
     
       5. The silver halide color photographic photosensitive material of claim 1, wherein Y represents an aryl group which is substituted or unsubstituted and has from 6 to 20 carbon atoms. 
     
     
       6. The silver halide color photographic photosensitive material of claim 1, wherein Xl is an alkyl group having from 1 to 10 carbon atoms. 
     
     
       7. The silver halide color photographic photosensitive material of claim 1, wherein Y is a phenyl group having at least one substituent group in the ortho position. 
     
     
       8. The silver halide color photographic photosensitive material of claim 1, wherein Z is a five or six membered nitrogen containing heterocyclic gorup which is bonded to the coupling position by a nitrogen atom, an aromatic oxy group, a five or six membered heterocyclic oxy group or a five or six membered heterocyclic thio group. 
     
     
       9. The silver halide color photographic photosensitive material of claim 1, wherein the coupler of formula (1) is represented by formula (2): ##STR16## wherein X2 has the same meaning as that described in formula (1), Alk represents an alkyl group having from 1 to 10 carbon atoms, Ar represents a phenyl group which has at least one substituent group in an ortho position and Za represents a five or six membered nitrogen containing heterocyclic group which is bonded to the coupling position with a nitrogen atom, an aromatic oxy group or a five or six membered heterocyclic thio group. 
     
     
       10. The silver halide color photographic photosensitive material of claim 1, wherein the coupler of formula (1) is added to a photosensitive silver halide emulsion layer or to a layer adjacent thereto. 
     
     
       11. The silver halide color photographic photosensitive material of claim 1, wherein the coupler of formula (1) is present in an amount of 0.0001 to 0.80 g/m 2  when a photographically useful component is included in leaving group Z and when there is no photographically useful group component in leaving group Z the amount of the coupler of formula (1) is 0.001 to 1.20 g/m 2 . 
     
     
       12. The silver halide color photographic photosensitive material of claim 1, wherein said coupler of formula (1) is fast to diffusion. 
     
     
       13. The silver halide color photographic photosensitive material of claim 9, wherein said coupler of formula (1) is fast to diffusion.
